    Niekonwencjonalne rozwiązania w procesach przeróbki węgli kamiennych
    (2007) Płonka, Andrzej; Śmiejek, Zygmunt
    Considering and describing problems of raw coal processing the following conclusions can be reached: - in common known and used technologies of coal feed preparation a technology modules for coal processing of grained building aggregates out of waste rock is not noted, - so far disludging of raw coal feed in a washer jig before processing takes place for grain size exceeding 0,5 mm, - so far processing in a washer jig is carried out for a majority of grain sizes over 0,75 mm, - no effective proposal of classification and sludge dewatering for size over 0,05m are noted. The proposals presented in this article, being a trial of its authors to optimize processing, are based on the following findings: - raw coal quality when considering ash contain is decreasing, processing installations are not modernizing in a proper manner, therefore technology installation improvement requires constriction of new modules for stone removing which can not be carried out as per analogy to the existing solutions, - common used desludging of raw coal has been replaced by effective process applied for grain size much bigger to the existing so far, - processing in a fine jig is carried out for size over 0,2 mm, - classification and dewatering of sludges being processed is carried out in an innovative manner for grain sizes over 0,05 mm. This article presents new model of technology and equipment as well as modern approach to raw coal processing.
